Internet Connection Seems To Drop Offline Intermittently
Jan 15, 2013
My internet connection seems to drop offline randomely while surfing the net. It basically results in yahoo or google freezing for 20-60 seconds before unfreezing and running flawlessly again. I seen a previous post that requested the individual hit start, run, cmd, and enter tracert google.com.
Windows 7 Professional
Service Pack 1
Intel Core 2 Duo CPU E8400 @ 3.00GHz
My RVS 4000 v1 router firmware version 1.3.0.5 has been intermittently going off-line ... a reset of the power resolves the issue temporarly. My plan was to update the firmware but I haven't been able to download an uncorrupted version of the firmware file on the Cisco support site. The file downloads as a zip file but the winzip program says that the file is not in a valid zip format and cannot open it.
I have a network that has a pair of 6500 switches on either end, running HSRP. In between each 6500 are two to three ruggedcom switches. They are connected to each other and the 6500's by trunk ports in a straight line. The 6500's see each other as CDP neighbors, and the 6500's can see the rugged- com as LLDP neighbors (ruggedcom only supports LLDP).
The issue is that randomly devices on the ruggedcoms will drop offline and then come back. The problem is that the devices that drop offline are all in the same VLAN, so it appears like a virus - i.e. one device drops off, then multiple. Eventually the HSRP starts flapping between the two 6500s and this causes havoc on the network.I'm almost to the point of taking a laptop and plugging it into one of the ruggedcom's to see traffic, but the issue is that the ruggedcoms are outside in cabinets that laptops shouldnt be exposed to.
Recently been taking my Laptop installed with Win7 Pro to a Friends and was sharing his Wireless connection from Belkin ADSL2+ wireless router and notice that every now and again the wireless connection would drop out and the only way to regain a connection to the reset the router. My friends network has two laptops on it connected wirelessly with Windows XP home edition SP3, and a Desktop PC with XP also on connected to router Via Ethernet, also a Windows Home Server and XBOX 360 also connected by Ethernet, My friend since updated his laptop to Windows 7 Home Premium and is using the Wireless connection which now finds intermittent loss of connection which can only be restored by Resetting the Router. why a Router should lose connection just by connecting a Win7 laptop wirelessly or is there more to it than that.
The old 615 has been working very well for some years now, but the last couple of days we have had to turn it off and on again to get internet. It has happened 3 times in the last 24 hours. The globe light on the router remains green, and the notification icon on windows 7 doesn't show any problems yet we cant connect to the web. I've been looking on the forum and trying to understand some of the solutions and checklists already posted, but they don't make a whole load of sense to me unfortunately.
The firmware on the router is 2.27. The only change I have made to the system is that my wife's lan card seems to have died a death last week, and her computer is now connected by wireless. My computer is now the only one connected to the router by a lan cable.
There is something I don't understand. Under setup / network there is a dhcp reservations section. Pretty much every device seems to have a reserved IP address, and some of the devices that are reserved we no longer own. My son does gaming and wants a constant IP address, and my computer might need a permanent IP (don't know - just guessing here). Should all the other computers be allowed to sort themselves an IP every time they log on? Most of the devices have expires never, and some of the devices have the blue link that I can click for revoke and reserve with a time by them.
Am I barking up the wrong tree here and this lot has nothing to do with the dropping connection? What do the revoke / reserve and times mean? What happens when the lease runs out? Will the connection drop on that computer and it will have to try and connect itself again, or does it start a new lease every time it logs on to the router?
I have a Linksys Wireless-N Home Router, WRT120N to be exact, and I have been having problems with my wireless. My wifi losses internet connection intermittently. This does not happen when I am connected directly to the router with a Ethernet cable. I have redone all the settings many times(like 6) and Im still having the same problem. I really dont want to have to buy a new router
I've been having some issues with my DIR-825, it's been intermittently dropping internet connection. This is across multiple OS (Win 7, Ps3 OS, iOS, etc.
For eight months we have not had any problems with our new WRVS4400N (V2.0.2.1) connected to a Verizon/Westell 6500 to provide DSL internet for our network with DHCP on our server... No changes have been made to the router or modem since initial setup; but, then it started -- Our internet connection would drop intermittently. Sometimes every 5 or 10 minutes - sometimes every hour. Verizon has tested the lines which came up ok, then they sent a tech who changed the wire pair coming into the building for the DSL line and retested the lines which again came up ok, then they provided us with a new modem (now a Verizon/Westell 7500). After all that, the DSL still connects then disconnects intermittently. I am now wondering if the issue lies with the WRVS4400N.
I have been having problems with my Internet the past couple weeks. If I am watching a video, it doesn't matter which site, the video will stop and start from the beginning or the video will just stop altogether and I have to refresh the page. Another problem that happens while browsing, it will take about a minute for a page to load. The computer I am using is wired right into the router.
The rest of the family's computers the apple tv and the roku are wireless. I have been hearing complaints from them and have witnessed the laggyness. While streaming videos on the roku or apple tv, the video will stop and say video is not available or no connection. This is what I get from ipconfig/all

Ok, I have a huge problem with my wireless connection. It will constantly lose connection to the internet from my PC, IPod, Laptop etc. What will happen is a yellow warning triangle appears which tells me I've lost internet access. I have had the modem checked and replaced by the ISP with no success so it's likely that it's not a problem on their end. I've changed the wireless channel to move it away from my neighbours with no success.
Here is a copy of my ipconfig /all when the connection dropped out:
C:UsersKevin>ipconfig /all Windows IP Configuration Host Name . . . . . . . . . . . . : Kevin-PC
I have a Cisco RV120W router with 1.0.4.10 firmware. The router drop the internet connections, freeze/timeout in admin interface randomly. How can I determine that this is the router's fault, or if it's the switch / internet access is causing it?
I’ve bought a router, and a wireless antenna for my laptop, since I have a high-speed internet outlet in the living room, but I use my laptop in the kitchen (I don’t have any other pc). So I’ve configured my Linksys WRT120N router in the living room, unplugged the ethernet cable from my laptop, plugged the wireless antenna in the kitchen, and everything was working fine with the wireless network. After about one month I was not able anymore to enter my network with the security key, there was actually no prompt for the security key, just a message “Cannot connect to the network”. I then had to reconfigure the router, going to the router IP address (I used the default settings, a blank for username, and “admin” as a password, as per instructions), use another network name, security key and password, and was able to start again a wireless network with the wireless antenna as before. This problem represented other 3 times (in the last 3 months), and was working fine, but now I cannot reconfigure the router anymore, since the IP address doesn’t accept BLANK/ADMIN anymore, and if I go ahead and reconfigure the router a message says I have to use the default settings in the IP address…
A lot of times our users will have a bad connection from where they are connecting in from. Their Internet connection will drop and the VPN Client disconnects but on our Cisco ASA5520, the connection will still be connected and when their Internet connections comes back, they are not able to connect as the session is still up on the 5520. Is there a way to make the connection clear quicker? I have IKE Keepalives on the RA Profile (Confidence 300 seconds, Retry Interval 2 seconds) but it seems to keep the session longer than that. Is there anything I can do to make the connection clear quicker?
I purchased a WRT110 router about a 18 months ago. I am currently experiencing an issue where the wireless connection to the router will become randomly erratic. My internet connection will slow down or drop entirely. Sometimes my laptop will disconnect from the router entirely. I don't think it's the wireless card in my laptop since I have seen the issue on my desktop using a wireless N USB adapter, my Nintendo Wii, and my wife's Macbook, all within the last week.
I am positive it is the router. I set up a coninuous ping command to the router accross my laptop's wireless using "ping -t 192.168.2.1" in a command prompt. Most of the time, the round trip is 1 to 3 ms or <1 ms. When I am experiencing the connection issues, the ping time will rise significantly, sometimes going as high as 2000 - 3000 ms. About 25% of time, the ping will just time out. When this starts happening, the only way I have been able to restore proper connectivity is to manually reboot the router. The issue eventually re-appears. Sometimes in a few days, sometimes in as little as five minutes. I've gone so far as to restore the router to factory defaults and reconfigure it, but that has not made a difference.
I have experienced some strange behavior of WiFi connection using WRT320N router. ISP provides me the internet in 2 modes (day and night). During day mode max speed is 24 Mb/s and during night 60 MB/s. Modem ADSL (Cisco EPC3010) is connected to Linksys WRT320N and on router is configured WiFi.Now issue. In the day mode everything is perfect. Cable connection gives me 24 MB/s and WiFi connection around 22 MB/s so not so bad. However when my internet speeds up to 60 Mb/s (cable connection via router gives exactly 60), WiFi connection instead speed up as well, just drop to max 17 Mb/s. I have tied several different settings on the router including changes in WiFi band, channel width, different channels (now channel is setup to 1 which is maybe not totally free but no so occupied) and others but unfortunately without significant improvement (in many cases connection just slowed down more).
And some details: Wireless configuration (now) Band: 2.4GHz Mode: Wireless-N only Channel Width: Auto (20MHz or 40 MHz) Channel: 1
Wireless adaptor: Intel Centrino Advanced-N 6230 (I know that this doesn’t mean anything but Win7 shows that connection is established with speed 144MB/s)Router firmware and WiFi card updated to the newest version.
We recently moved and upgraded our internet service from 1.5 Mbps to 4Mbps with CenturyLink. However, since our service was activated last Thursday, the internet connection intermittently drops and will not recover unless I reboot the modem. The period of up-time will last anywhere between fifteen seconds to several hours, usually falling along the five-to-ten minute range. No difference when using ethernet/wifi. The DSL light stays on, and the Internet light remains on as well.
I have a desktop computer and a laptop computer both running Windows 7 Home Premium. The desktop is connected to the router directly and the laptop is connected to the wireless network. When I restart both computers, I can see and access the other computer through the home network without problems. But after a while, sometimes just a few minutes, I can only see the other computer but cannot access it. Sometimes, I cannot even see the other computer. If I do a "ipconfig /release" and a "ipconfig /renew", it may sometimes correct the problem for a while.
I have looked at many related discussions on the web and none of the suggestions work for me.I have the firewalls disabled on both computers, as well as the ipv6 and IP service. I have also disabled the Bonjour service.I have turned a number of services, such as computer browser, server, workstation and many others to automatic as people suggested.
Only at my home network, my HP Pavilion Laptop wifi will sporadically just stop identifying the router. The router (and Intel) shows enabled and good signal and my husband's laptop shows no interruption. My wifi keeps trying to reconnect but can't. I have to power off the router to reboot it so my wifi connects again. This is really annoying...
ISP - Comcast Cable Internet Modem model SMCD3GNV wired/wireless combo (2 pcs connected 1 wired 1 wireless)When the connection is online, the speeds are fine- the issue is the 2-3 times a day when the connection drops off. The error that we are getting is "cannot connect with primary dns server" however in our attempts to restore the connection we have: [code] is there some issues in the area that we are not aware of? being that the signal levels are within range what do you think the problem resides in? FYI, both connections, the wired and wireless connections both have connectivity issues equally.
I installed the RV220W Router in my office about 2 weeks ago and everything works perfectly for 3-4 days but then my connection drops out and the router must be restarted to restore connectivity. When I say the connection drops basically the internet connection drops out and my network connections drop shortly thereafter. Usually the wireless connections lose connectivity followed within a few minutes by the wired connections.
Is there something in my firewall settings that could cause this issue? I have checked with my ISP to verify there are no problems on their end.
I have a WAG160N v2 and a UK Online broadbad account, windows xp. The connection intermittmently drops out, approx 15-30 times per day. I have spoken to my ISP and had the line checked (no packet loss issue), checked the settings on the router against my ISP and also updated the router firmware all with no improvement.
I've been having issues with my e2500 router. I've found my connection dropping occasionally both with a wired connection and wirelessly on other computer. My desktop is connected directly to the router via ethernet and I've been keeping an eye on my network preference pane. Every 10 minutes or so the connection will be lost and computer says the cable is unplugged. It then resolves after 2 minutes.
I'm running OSX 10.8, firmware 1.0.07. Done a factory reset, power cycles etc. Configured with Cisco connect and manually multiple times. I've swapped out ethernet cables just to be sure it wasn't a cable issue.
Internet is fine when I've got the computer hooked up directly to the modem. No connection issues.
FSD 7632-4 Router.Have this 2006 router which has started dropping the connection and/or slowing it down intermittently. Before I replace it, would like to update the firmware. Have downloaded the update but cannot log-in on the setup utility page as I cannot remeber my password (apparently it is not set to blank!).
I have a server in a DMZ behind the ASA, connections to this server work sometimes and then fail others, so I dont think i'm looking at an ACL or NAT problem here.The syslogs report a SYN Timeout,I have taken a trace on the ASA, it seems that a SYN-ACK does come from the destination server within the 30sec timeout, but its not passed through the ASA back to the source ? there is one odd thing, what seems to be an out of sequence ACK from the destination which arrives before the SYN-ACK at the ASA, i'm wondering if this might be the problem ? This only occurs on the connections which fail, the connections that work, the destination responds quickly to the initial SYN, and the 3way handshake completes.

Can't figure out how to setup computer to access the internet. When I click on Internet Explorer the error is "Web page you requested is not available offline
I have a Netgear DG834G v3 ADSL router which I have had since early-2007.
When I work from home I connect to office networks on a Win7 machine via a Rackspace-provided VPN using Cisco System VPN Client 5. It works well, except for one issue that is costing me time every working day.
I get intermittently disconnected from the VPN, without any warning or apparent reason.
Since I bought the router 5-6 years ago I have had no need to update firmware, so other than ISP configuration I have had no need to change the router at all and I can say it's worked well for me.
What would be the reason for my VPN connection dropping? Is this an ISP issue (my ISP is Carphone Warehouse/TalkTalk) that I have to take up with them or is it more likely a hardware problem with my router or a VPN configuration issue?
My instincts are to not look into VPN config at the moment as I know a colleague who uses the same VPN through a different router and ISP can stay connected for hours, even overnight.
[code] Whenever I am browsing online, every once in a while the internet just cuts out. It still says I am connected to my wifi network, but there is "limited or no connectivity." Whenever it happens, everything on the network loses its internet at the same time. In the household, there is one PC (mine), one Mac (my wife's), one iPod touch, and 2 iPhones that all connect to the wifi. The vast majority of the time, when this problem occurs, simply unplugging the router and then plugging it back in fixes the issue.Sometimes however things are different. Especially lately, I sometimes get an "IP conflict" error message. It says another device on the network is using the same IP address. Sometimes with this error simply unplugging and replugging in the router works. Sometimes the router has to be reset twice before things start working again with this error. The error doesn't happen every time the disconnect occurs, but it seems to be getting more frequent lately.Sometimes the disconnect happens when I am playing an online game that requires a constant connection to the internet. Sometimes this goes as usual, where a single router reset fixes the problem. However, sometimes this situation gets more complicated. One game in particular (League of Legends, if it matters) has this problem all of the time. When the internet disconnects while this game is playing, I do not get the "limited or no internet" warning. Instead, the computer seems to think that it is connected, and that the internet is working.
During this scenario, resetting the router once is never enough. After resetting once, the wifi reconnects and now it realizes something is wrong. After the first reset, the computer seems to "realize" something is wrong after all, and I am connected to the network but this time with the "limited or no internet" warning. A second router reset after this usually fixes the problem.Last night the worst disconnect happened yet. It was in the middle of a game, and the internet cut out, with no warning on the network. After one router reset, the wifi network reconnected immediately with an "IP address conflict" error, and then I was connected with "limited or no internet" on the network. I did the second router reset as usually required, but nothing happened. After a second and a third reset, there was still a permanent "limited or no internet" warning.I tried hardlining in directly to the modem and there was still no internet. Running the network diagnostic on my laptop fixed it however and I was connected to the internet. However, wifi still would not work, even after trying the diagnostic again. Running the diagnostic came up with an error that the DNS server was not responding and so nothing could be done.This time I reset everything. Unplugged both the router and the modem and left them unplugged for 30 minutes. When I turned everything else on again, same issue. Connected to the wifi network, but "limited or no internet." I unplugged everything again, left them overnight, and this morning after plugging everything back in the internet was back.A few final points I think might be relevant:
1) When checking the system event logs, it's usually a DNS error that I get (see event logs, 1st attachment). 2) This disconnect error seems to be more prevalent when more devices are on the network. As I said, they have gotten more frequent lately, especially the IP conflict warnings, since the 2 iPhones were added a few weeks ago. 5 months ago when it was only my PC on the network, these issues were practically non-existent. 3) It's a Belkin wireless g-plus router. Model # F5D7231-4 version 1213. It is an older router. 4) This has been happening for almost a year, but just recently gotten so bad I have to get this fixed, especially after last nights that could not be reset no matter what. 5) I'm not sure the disconnects have ever happened why the PC is not connected. That may not be relevant however, because my PC is almost always on since I work from home, while the iPhones, iPod touch, and my wife's Mac are only connected periodically. 6) This error has occurred while my PC is the only device connected to the wifi network, but it seems much less frequent. 7) The time the error seems most likely to occur is when another device connects to the network, such as when my wife first gets home from work. This is not exclusive however, and the DC's can happen at any time.
I've seen that people want ping tests and ipconfig /all tests so I will post mine. I will edit my post with the same tests done the next time this dc happens. I've also included a screenshot of that xirrus wifi program. [code]
I've recently just moved house and we got Virgin Media 50mgs broadband installed with their wireless super hub which is also a Netgear product.However I first noticed up in my room I have weak signal on my wireless devices I have my Dell laptop, xbox 360 and desktop pc with wifi card.I researched this and went out and bought a Netgear wireless extender:
[code]...
Now this does work it gives me excellent signal but it keeps dropping the connection which is extremely frustrating when playing the xbox or on an online game on the pc.I contacted Netgear and all they suggested was updating the firmware
Ok so my internet connection has recently started disconnecting and reconnecting every 5 mins or so. It has never done this before and has started doing it out of the blue. It doesn't even appear to have cut out by the icon at the bottom but it does stuff like stop youtube videos from loading or when I am playing online poker or online gaming it will cut out for about 30 seconds before reconnecting again.
The internet on my laptop only works intermittently. After a minute or so of initial use, it stops working and when I run the troubleshooter it discovers that the default gateway is not available, and then it says that it has fixed the problem. However, after only a minute or so more, the internet once again fails. I have tried the "run>cmd>enter>ipcongfig>enter" and found that the numbers for the default gateway are the same on my laptop as for a laptop that does work.
I'm setting up a small network (one server, two clients) to create photo sales kiosks at an upcoming outdoor event. I will need internet access for processing credit card payments but there won't be any wi-fi or ethernet internet access on the site so I'll need to utilize my iPhone's 3G connection. I recently installed "MyWi" app which can tether the 3G and even create a personal wi-fi hotspot but unfortunately it only works in ad-hoc mode, not infrastructure.So far, the wired LAN is working great on my three Macbooks, using a Linksys (DD-WRT) router. Also, the wi-fi hotspot is working great to provide internet to all the computers. The problem, of course, is that I can't have both connected at the same time or else everything breaks. I've tried doing an iPhone-USB-Macbook tether and then sharing the connection via ethernet but the internet doesn't get through the router (because I don't have a clue of how to configure the router for this). I've also tried setting my router (DD-WRT) to do a client-bridge of the iPhone ad-hoc wi-fi, but again, it's way over my head and didn't work.
